And it's not just replacing current electrical generation - there would probably have to be a two or three ORDER OF MAGNITUDE expansion of electrical generation capacity.
100 to 1000 times more electricity? Really?
2014: 136.78 billion gallons of gasoline consumed.
At 33 kWhr/gallon, that's 4,514 billion kWh if you completely ignore any differences in efficiency.
2014: 4,093 billion kWh of electricity produced.
So at the absolute WORST case, it's a little more than double. But when you figure that an electric vehicle uses that energy nearly three times more efficiently, it's under 50% more.
And that's if you go ahead and replace *everything* that burns gasoline with electric, which of course you wouldn't.
Then after all that, producing ~50% more kWh does not translate into needing ~50% more power plants. You would need to factor in some diversity factor as not all power plants are running all the time nor at full capacity.
